The spacing of fire sprinklers should be adjusted according to different sprinklers and environments, and the setting of fire sprinklers should comply with the Code for Design of Automatic Sprinkler Fire Extinguishing System. Details are as follows:

The corresponding provisions in Code for Design of Automatic Sprinkler Fire Extinguishing System GB50084-2005:

7. 1.65438+ When there is an obstacle near the nozzle, it shall comply with the provisions of Section 7.2 of this specification or increase the nozzle to compensate for the water spraying intensity.

7. 1.2 The arrangement of vertical and drooping nozzles, including the spacing of nozzles on the same water distribution branch pipe and the spacing of adjacent water distribution branches, shall be determined according to the water spraying intensity of the system, the flow coefficient of nozzles and the working pressure, and shall not be greater than the provisions in Table 7. 1.2 and shall not be less than 2.4m.

In addition, except for the ceiling sprinkler and the sprinkler installed under the ceiling, the distance between the splash plate of the vertical and drooping standard sprinkler and the roof should not be less than 75mm and should not be greater than150 mm.

Showers should be installed above the passages of libraries, archives, shopping malls and warehouses. The horizontal distance between the nozzle and the protected object should not be less than 0.3m；; The minimum vertical distance between the nozzle splash plate and the protected object shall not be less than that specified in Table 7. 1.5.

Extended data:

Fire sprinklers are used in fire sprinkler systems. When a fire breaks out, water overflows through the splash plate of the sprinkler to put out the fire. At present, it is divided into drooping nozzles, vertical nozzles, ordinary nozzles and side wall nozzles.

Pendulous type

Swing sprinkler is the most widely used sprinkler. It is installed on the water supply branch pipe in a swinging way, and sprinkles water in a parabolic way, spraying 80 ~ 100% of the total water to the ground. Protect rooms with ceilings, and arrange sprinklers under the ceilings. Drip sprinklers or ceiling sprinklers should be used.
